Cross-domain code list

SDMX code list meeting at least one of the criteria below:1) Potential application across all statistical domains; 2) Code list maintained by the SDMX Statistical Working Group (SWG) on its initiative; 3) Code list recommended as CDCL by the SDMX SWG although they are in principle maintained by third organisations.

1) Potential application across all statistical domains. Examples: CL_OBS_STATUS, CL_CONF_STATUS, CL_DECIMALS, CL_UNIT_MULT, CL_AREA. Explanatory note: Key term for this criterion is "potential". These code lists must not necessarily be implemented in all Data Structure Definitions (DSDs) but they potentially could. For example, code list Unit multiplier could possibly be used in all implementations dealing with statistical figures but some implementations might not see the need for such a dimension because the statistical values do not require it, e.g. average number of children per household. Inversely, in this example a code list for decimals will be absolutely necessary. 2) Code lists maintained by the SWG on its initiative because 1) they are intended for broad use within the SDMX community and 2) there is a strong need for harmonisation across domains which are not necessarily closely connected with each other. Examples for case 1: CL_AGE, CL_CIVIL_STATUS, CL_FREQ, CL_TIME_FORMAT, CL_SEX, CL_ADJUSTMENT. Explanatory note: By proposing such code lists it is hoped to promote harmonisation across domains and provide ready-to-use artefacts to implementers. Example for case 2: CL_ACTIVITY. Explanatory note: International activity classifications are typically used in different statistical domains (e.g. economic versus social statistics). Without an established CDCL made available in centralised registries, the risk is that one domain develops a code list without taking into account the fact that other domains might use the same classification system. 3) Code lists recommended as CDCL by the SDMX Statistical Working Group (SWG) although they are in principle maintained by third organisations. Examples: CL_AREA (based on the ISO 3166 alpha-2 codes for countries); CL_CURRENCY (based on the ISO 4217 3-character codes for currencies). Explanatory note: In these cases, the value added by the SWG is to propose guidelines on specific methodological issues, e.g. how to code a country that has been split into several new entities.
